Umm is is not dangerous until someone else (not the cyclist/s) brakes the law and endangers all. Cyclist usually only endanger themselves, not others.
If the cyclist/s is doing something illegal - report it. Taking the law into your own hands leads to trouble, don't do it. Easier to say than do, but there you go.
